1. A diverter spout for dividing fluid flow between two flow paths, the spout comprising: a housing defining an internal flow channel with a restricted aperture therein, said aperture having an intake side and outlet side;a carriage transversely movable across said restricted aperture;a linkage between the carriage and a control for causing the carriage to move relative thereto when desired; anda rollable gate mounted on the carriage;whereby the rollable gate can be caused to roll along a side of the aperture to thereby facilitate control of diversion of flow between the two flow paths if the spout is linked to a fluid supply and fluid is supplied to the spout;wherein an axle is mounted on the carriage, and the rollable gate is, rollably mounted on the axle; andwherein the axle is mounted in slotted hub structures of the carriage so as to permit the axle to move towards and away from the aperture in a direction transverse to a direction of movement of the carriage. 2. The diverter spout of claim 1, wherein the linkage comprises a rod passing through an upper wall of the housing and a knob mounted at an upper end of the rod outside the housing. 3. The diverter spout of claim 2, wherein a resilient member biases the carriage towards a position in which it is not completely closing off the aperture. 4. The diverter spout of claim 1, wherein the diverter spout is a filler spout suitable to divide water flow between a bathtub when water passes through the spout and a shower outlet when the rollable gate restricts flow through the aperture. 5. The diverter spout of claim 1, wherein the internal flow channel is an axial channel and an adaptor ring is provided at an intake end of the axial channel suitable to link an intake supply line to the spout. 6. The diverter spout of claim 1, wherein said rollable gate is comprised of a resilient material. 7. The diverter spout of claim 6, wherein the rollable gate is formed of a rubber. 8. The diverter spout of claim 1, wherein said intake side of the aperture includes a chamfer forming a seat for the rollable gate. 9. The diverter spout of claim 1, wherein the rollable gate is in a form of a ball having a through passage for accepting an axle. 10. The diverter spout of claim 1, wherein said housing includes an aerator at its outlet end. 11. The diverter spout of claim 1, wherein the rollable gate can be caused to roll along the intake side of the aperture. 12. The diverter spout of claim 1, wherein the carriage is located on the intake side of the aperture. 13. The diverter spout of claim 1, wherein the slotted hub structures extend in a direction that is substantially parallel to an axis of the internal flow channel. 14. The diverter spout of claim 1, wherein the carriage comprises an open position and a closed position, and wherein the slotted hub structures are configured such that, when the carriage is in the closed position, the rollable gate moves towards the restricted aperture in response to fluid flow through the internal flow channel.
