Add Ability to Fully Split Path

[j-schwar]

A new feature should be added which allows for fully breaking down a file path. The result would be a structure containing the various parts of the path as attributes.

For example:

type FilePath = struct {
	Directories []string
	Filename    string
	Extension   string
}

Along with this, various methods should be added to allow for manipulation of the separated file path as well as the ability to turn it back into a string.
