Implement `reflect` #53

Closed p-gw closed 7 months ago

p-gw commented 7 months ago

This pull request implements reflect and reflect! functions, as well as the keyword argumement reflect to rotate.

Reflect modifies the rotated loading matrix by swapping signs columnwise such that the sum of all factor loadings is non-negative.

This is a breaking change, since the default is reflect = true in rotate.
