make unit test suite cross-platform #17
Description
Currently, unit tests executed via go test require a Unix-like environment for execution.
This is due to a Unix-style relative path being set as CaTestFolder in goca_test.go as well as some Unix-style relative paths in the caPathInit() function, currently defined in storage.go, specifically for handling testing.
Improving the cross-platform compatibility in these locations would make it easier to support Windows as a development platform.
