EnkiUtilities is a fairly vague collection of methods, classes, and class categories that I've developed over the years that I find personally useful when writing iOS apps. Feel free to use any or all of these in your apps.
The categories, in particular, contain code that I've mostly not written, but rather found on line, mostly likely on stackoverflow and I've linked to the the authors when I can. I specifically do not claim copyright no them, they are not my work, just work that has been released into the wild for public consumption. (To be strictly legal, I should contact these authors for permission since they have not specified what licenese they've used, but that really seems like over kill for something that is short and published by the others for the purpose of reuse!

| + (BOOL) AlmostEqualRelative: | (float) | A | |
| and: | (float) | B | |
Returns TRUE if the two float numbers are almost equal. Be sure to read http://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/ This is a good algorightm for Enkid's applications, for many applications this is not at all good. Read and understand

| + (UIColor *) defaultBackgroundColor: | (UITableViewCell *) | inCell |
Returns the background color of tabbed group cell. This color changed between iOS4 and iOS5
Note how we use the static UIColor object as a cache so we only have do some expensive operations once.
