ld_mirrorMe v1.5.0

Edit: Source is now available on GitHub.

I was surprised by the response this tool had, so I'm releasing v1.5.0 to help some people out, it'll be good to hear how you guys use it.
Alongside my softCluster script, you'll definitely notice a speed increase in your workflow.

Download it here (mediafire link).
Download, extract and place script in maya's script directory and use

import ld_mirrorMe
ld_mirrorMe.GUI()

It's features are shown on this much quicker demo (v1.0.0), supporting multi-mirroring for all modes.

Full details:
 - 3 modes:
     1. Curve - mirrors nurbs curves, ideal for mirroring rig controls,
     2. Mesh - mirrors geo, ideal for mirroring blendshape targets,
     3. Deformer - mirrors only clusters (at present), uses object's pivot for mirroring.
 - multi-mirroring on all 3 modes,
 - choose mirror axis,
 - search and replace,
 - alter new objects position (currently either world 0, target, mirror or original - depending on mode),
 - world position/rotation based, will work wherever or whatever the targets connected to,
 - entry objects names retained, if multiple copies needed (ideal for multi-clustering),
 - colourize option for Curves, if given curve is coloured (transform or shape), its mirror can be assigned a different colour,
 - quick and simple to use.
