                           get_spike_data

Qualitative test for presence of spike in noisy data. Also records salient spike information
 for quantitative comparisons later.

Criteria: ensure a maximum occurs, and that this is away from endpoints of traj
 "Uniqueness" of this maximum can only be determined for noisy data using a height
 tolerance.

Assumes spikes will never bunch up too much so that more than spike occurs in the
 spacing_tol window.

Finds maximum position using a quadratic fit.
