Miscellaneous Do's and Dont's

SdfPath::GetString() gives a fully unrolled, representation of any location in namespace, and is very useful for debugging. However, it is rather expensive, and may cause a globally-shared cache to be populated. Don't call it (or SdfPath::GetText()) in any performance-critical loops, and in general, if using it for diagnostics, only call it inside a block that is guarded by your debug flag.
