Updated all nodes so parameters are located in a "parameters" variable.
Started writing a generic node model whose behavior is defined in a json file. Should be able to replace all generators so far.
Wrote json files for bricks and noise nodes.
Started preparing a custom node.
Started adding the "remote" node, that can control important parameters of the graph and save/restore configurations of groups of parameters. This should help creating easily configurable materials.
Added new "mosaic" example
