Move normalization functions/classes to a new directory

[Jari Häkkinen]

We will probably have several normalization algorithms in yat. Move current normalizers to .../yat/normalize and, of course, add new normalizers here.

[Peter]

All other namespaces are nouns such as utility, random, classification, statistics, and regression, and not verbs such as utilize, randomize, classify, (how do you verbalize statistics?), or regress. I think we should stay with that style because it makes it uniform, in other words, I would prefer normalization rather than normalize.

When we have decided on the name, initial things to do are

• add the directory
• fix the build to include the new directory
• add component in Trac
• add namespace in doc/namespaces.doxygen

Replying to peter:

normalization is okay with me.

[Peter]

(In [1429]) refs #416 - added directory and modified build

[Peter]

(In [1430]) added blurp in namespaces.doxygen - refs #416

[Peter]

rev [1429] does not compile because there is no source for the normalization lib. I'll fix it tomorrow, Monday.

[Peter]

(In [1432]) refs #416 moving quantile normalizer to new dir. Also moved the algorithm to a class (rather than free function).

[Peter]

I've changed my mind regarding the name and will change to normalizer, which is in line with classifier.

(In [1497]) changing name to normalizer - closes #416
