can we have to_ucsc of some sort somewhere ?

[sergpolly]

in an effort to unify handling of regions throughout cooltools/bioframe we should have something like to_ucsc formatter somewhere , shoudn't we ?

e.g. to avoid code like that: regions.apply(lambda x: "{}:{}-{}".format(*x), axis=1) ...

There is something in cooler i believe but should it be in bioframe instead ?

[gfudenberg]

this should now be in bioframe.core.stringops
