FileTool: Layout File Splitting

The FileTool can be used to split a large layout file into a collection of smaller layout files.

For splitting, the command line takes the form:

filetool [-set variables] -split split_args

This mode will write output files corresponding to the partitions of a square grid logically covering all or part of a specified cell in a given layout file. The output files contain physical data only. These files can be flat or hierarchical.

The operations and split_args are identical to those of the Xic !splwrite command (19.2.4).
