/// The gestures loaded must conform to a naming convention where each example of a particular gesture is named
/// with the same string, followed by a numerical identifier for that example. As in:
///
/// circle01.xml // circle gestures
/// circle02.xml
/// circle03.xml
/// square01.xml // square gestures
/// square02.xml
/// square03.xml
/// triangle01.xml // triangle gestures
/// triangle02.xml
/// triangle03.xml
///
/// The same number of examples should be read in for each gesture category. The testing procedure will load a
/// random subset of each gesture and test on the remaining gestures.
///
/// <b>Warning.</b> This process will throw an exception if the number of gesture examples for each gesture is
/// unbalanced.
