// Description:
// Returns a list with the deltas of adjacent entries in the given list, optionally wrapping back to the front.
// The list should be a consistent list of numeric components (numbers, vectors, matrix, etc).
// Given [a,b,c,d], returns [b-a,c-b,d-c].

// v = The list to get the deltas of.
// wrap = If true, wrap back to the start from the end. ie: return the difference between the last and first items as the last delta. Default: false
