What is claimed is: 1. A modular cargo container (1) assembled with FRTP composite sandwich panels where external container loads are distributed throughout the assembled panels by integrally thermoformed panel edges and edge assemblies, said cargo container comprising: a base (11) having a forward end (2) and a rearward end (4), and an edge rail (15) along said base's opposite sides and rear periphery said edge rail having an outer horizontal leg (19) and a vertical leg (21), three vertically planar panels (3, 5, 7), two opposite each other and the third located between the two, having an inner FRTP composite skin (23) being made of a fiber reinforcing a thermoplastic resin in a fixed proportion, an outer FRTP composite skin (25) being made of a fiber reinforcing a thermoplastic resin in a fixed proportion, a low density thermoplastic resin core (27) sandwiched between and integrally fixed to said inner skin and outer skin, a forward and rearward integrally thermoformed side edge (32), an integrally thermoformed upper edge (31), a plurality of integrally thermoformed radiused corners (38), an integrally thermoformed lower edge (29) which is attached to said base (11) along the length of lower edge (29) by a plurality of attachment means (39) attaching said lower edge to the vertical leg of said edge rail, a horizontally planar top panel (9) having an inner FRTP composite skin (33) being made of a fiber reinforcing a thermoplastic resin in a fixed proportion, an outer FRTP composite skin (35) being made of a fiber reinforcing a thermoplastic resin in a fixed proportion, said low density thermoplastic core (27) sandwiched between and integrally fixed to said inner skin (33) and outer skin (35), an integrally thermoformed periphery edge (37), a plurality of said integrally thermoformed radius corners (38), three right angled forward framing members (10, 12, 14) fixedly attached to forward end of said base (11), fixedly attached to forward ends of said side edges (32) of said opposite side panels and fixedly attached to periphery edge (37) of said top panel's forward end by a plurality of attachment means (18), a plurality of attachment means (20) to attach and assemble said vertical panels to each other along the length of their adjacent thermoformed side edges (32) and to attach thermoformed upper edges (31) of said vertical panels along their common length with thermoformed periphery edges (37) of said horizontal panel whereby the assembly of two side edges and the assembly of the upper edge to the periphery edge results into compact nested joints which distributes applied loads throughout the entire container assembly without the use of independent container stiffening members, a plurality of compact nested corner assemblies (132) resulting from the assembly of the radiused corners (38) of two adjacent vertical side panels and the radiused corner (38) of one horizontal top panel whereby said corner assembly is self sealing without the use of independent sealing means and said corner assembly distributes applied loads throughout the entire container assembly without the use of independent container stiffening members, an opening (6) serving as an access to the interior of container (1) and framed by said forward framing members (10, 12, 14) and forward end of said base. 2. The cargo container according to claim 1, wherein said low density thermoplastic resin core (27) is further comprised of polypropylene thermoplastic of a cellular honeycomb structure. 3. The cargo container according to claim 2, wherein the fiber reinforcing a thermoplastic resin in a fixed proportion of said inner skin (23) and outer skin (25) of said vertically planar panels is in a ratio of 50 to 75 percent of fiber to thermoplastic resin by weight and wherein the fiber reinforcing a thermoplastic resin in a fixed proportion of said inner skin (33) and outer skin (35) of said horizontally planar top panel is in a ratio of 50 to 75 percent of fiber to thermoplastic resin by weight. 4. The cargo container according to claim 3, wherein the fiber reinforcing a thermoplastic resin of said inner skin (23) and outer skin (25) of said vertically planar panels is fiberglass and wherein the fiber reinforcing a thermoplastic resin of said inner skin (33) and outer skin (35) of said horizontally planar top panel is fiberglass. 5. The cargo container according to claim 4, wherein the thermoplastic resin of said inner skin (23) and outer skin (25) of said vertically planar panels is polypropylene thermoplastic and wherein said inner skin (33) and outer skin (35) of said horizontally planar top panel is polypropylene thermoplastic. 6. The cargo container according to claim 5, wherein said base is further comprised of a plate (13), three edge rails (15) each at the opposite sides and rear periphery of said base and each edge rail having an inner horizontal leg (17), an outer horizontal leg (19), a vertical leg (21), and a plurality of attachment means (16) attaching said plate to said inner horizontal leg. 7. The cargo container according to claim 6, wherein said edge rails (15) are made of structural aluminum extrusions and said plate (13) is aluminum. 8. The cargo container according to claim 7, further comprising a closure means whereby said opening (6) is enclosed.
