/**
* This method returns the module that corresponds to the path passed as a parameter.
*
* @param name the name of the module we're looking for (e.g.: mod1.mod2)
* @param dontSearchInit is used in a negative form because initially it was isLookingForRelative,
* but it actually defines if we should look in __init__ modules too, so, the name matches the
* old signature.
* <p>NOTE: isLookingForRelative description was: when looking for relative imports, we don't
* check for __init__
* @return the module represented by this name
