possible to create dependency recursion

[ruby0x1]

consider:

haxelib git libA <libA url>
haxelib git libB <libA url>

If libA depends on libB, it will now infinitely query the dependencies of libB (since it refers to itself indirectly).

One solution that doesn't create inflexibility is a configurable maximum depth for the dependency tree, in order to catch this easier. Other options (like checking the haxelib.json content name vs the haxelib name) might work as well.
