Rename getSpacesWithinRange functions

[Itangalo]

The three functions for getting (matching) spaces within a range, either from a space or an arbitrary list of spaces, should be renamed. It is difficult to tell them apart.

Functions with similar names:

• myTrack.getSpacesWithinRange(originSpaceIndices, steps = 1, flatten = false, returnType = 'object', requirement = false)
• myTrack.getSpacesWithinRadius(point, radius = 1, shape = 'circle')
• mySpace.getSpacesWithinRange(steps = 1, flatten = false, returnType = 'object', requirement = false)
• mySpace.getMatchingSpacesWithinRange(property, value, steps = Number.POSITIVE_INFINITY, flatten = true, returnType = 'object')
