1. An evacuation system for a building comprising: at least one lowerable, multiple-platform, generally vertical transporter arranged for selectable communication with multiple floors of a building for simultaneous loading of persons onto multiple platforms of said transporter from said multiple floors; anda controller operative to position said multiple platforms at said multiple floors for simultaneous loading of said persons onto said multiple platforms of said transporter from said multiple floors and operative to subsequently lower said multiple platforms of said at least one transporter, when loaded with said persons, from said multiple floors to at least one egress level at which egress of said persons may safely occur. 2. An evacuation system according to claim 1 and wherein said at least one lowerable, multiple-platform, generally vertical transporter comprises: a plurality of stackable platforms arranged to be supported on multiple generally vertical supports, at least some of said plurality of stackable platforms being arranged in mutually spaced relationship, each in communication with a different floor of said building for evacuation loading. 3. An evacuation system according to claim 2 and wherein said plurality of stackable platforms are arranged in a mutually collapsed relationship when not in use. 4. An evacuation system according to claim 2 and wherein said plurality of stackable platforms are arranged in a mutually collapsed relationship following evacuation unloading. 5. An evacuation system according to claim 2 and wherein said multiple generally vertical supports comprise cables. 6. An evacuation system according to claim 2 and wherein said multiple generally vertical supports comprise rigid support elements. 7. An evacuation system according to claim 2 and wherein said plurality of stackable platforms each comprise a bottom support surface and a peripheral enclosing element. 8. An evacuation system according to claim 7 and wherein said peripheral enclosing element comprises a wall element formed of fabric. 9. An evacuation system according to claim 8 and wherein said fabric comprises at least one of a heat resistant fabric, a fire resistant fabric and a smoke resistant fabric. 10. An evacuation system according to claim 1 and also comprising at least one building mounted stabilizing element cooperating with said transporter for stabilizing said transporter against lateral forces. 11. An evacuation system according to claim 1 and wherein: said at least one transporter comprises a plurality of transporters; andsaid controller is operative to individually control individual ones of said plurality of transporters wherein multiple platforms of different transporters may be simultaneously positioned in communication with different groups of multiple floors of said building for simultaneous evacuation loading. 12. An evacuation system according to claim 1 and wherein: said controller is operative to simultaneously position said multiple platforms in communication with multiple egress levels of said building for simultaneous evacuation. 13. An evacuation system according to claim 1 and wherein said at least one transporter is also operative for lifting persons from said at least one egress level to said multiple floors of said building. 14. An evacuation system according to claim 1 and wherein said multiple platforms comprise nestable platforms. 15. An evacuation system according to claim 1 and wherein said transporter is building mounted. 16. An evacuation system according to claim 15 and wherein said controller is operative to selectably lower said at least one transporter to said at least one egress level in the absence of electrical power. 17. A method for evacuation of a building comprising: positioning at least one lowerable, multiple-platform, generally vertical transporter in communication with multiple floors of a building for simultaneous loading of persons onto multiple platforms of said transporter from said multiple floors; andlowering said multiple platforms of said at least one transporter, when loaded with said persons, from said multiple floors to at least one egress level at which egress of said persons may safely occur. 18. An evacuation method according to claim 17 and wherein said positioning comprises selectably positioning a plurality of stackable platforms, each in communication with a different floor of said building, for evacuation loading. 19. An evacuation method according to claim 17 and also comprising stabilizing said transporter against lateral forces. 20. An evacuation method according to claim 17 and wherein: said at least one transporter comprises a plurality of transporters; andsaid positioning comprises simultaneously positioning individual ones of said plurality of transporters wherein multiple platforms of different transporters are in communication with different groups of multiple floors of said building for simultaneous evacuation loading. 21. An evacuation method according to claim 17 and also comprising simultaneously positioning said multiple platforms in communication with multiple egress levels of said building for simultaneous evacuation. 22. A method for evacuation of a building comprising: positioning at least one lowerable, mutually spacable, multiple-platform, generally vertical transporter in communication with multiple floors of a building for simultaneous loading of persons onto multiple platforms of said transporter from said multiple floors; andlowering said multiple platforms of said at least one transporter, when loaded with said persons, from said multiple floors to at least one egress level at which egress of said persons may safely occur; andreducing mutual spacing between said multiple platforms following said egress of said persons. 23. An evacuation method according to claim 22 and also comprising stabilizing said transporter against lateral forces. 24. An evacuation method according to claim 22 and wherein: said at least one transporter comprises a plurality of transporters; andsaid positioning comprises simultaneously positioning individual ones of said plurality of transporters wherein multiple platforms of different transporters are in communication with different groups of multiple floors of said building for simultaneous evacuation loading. 25.
