Docstring clarification

[TheChymera]

1. Could you please clarify the following section of the docstring?

   COSgen/cosgen/function_crate.py

   Lines 207 to 211 in d68af52

   	a list of cosgen.sequence.Sequence objects. If the
   	function as an argument 'cross_over_fct' a cross over
   	function has to be set in advance using the set_cross_over
   	method. The 'cross_over_fct' parameter is then fixed to
   	this function.

   I assume it's just a typo as/has --- but I still don't understand where a crossover function would be specified, and what it means to have it fixed to this function.

2. COSgen/cosgen/models.py

   Lines 133 to 135 in d68af52

   	sequence. Colums of the desing matrix are a constant
   	(ones) a linear time course and the convolution of the
   	basis vetors with the sequence.

   This needs commas for the ennumeration, and *vectors has a typo, but most importantly: would linearly decaying time course not be a better description? Same here:
   

   COSgen/cosgen/models.py

   Lines 230 to 232 in d68af52

   	sequence. Colums of the desing matrix are a constant
   	(ones) a linear time course and the convolution of `hrf`
   	with the sequence.

3. Unsure what cave means here:

   COSgen/cosgen/models.py

   Line 456 in d68af52

   *CAVE*: A must contain already orthogonalized column vectors!!

[faymanns]

I think I fixed them all.
Not sure if the first one is clear now:

COSgen/cosgen/function_crate.py

Lines 205 to 211 in c9f980c

	This method sets a generate immigrants function used by
	the genetic algorithm. The function should normally return
	a list of `cosgen.sequence.Sequence` objects. `function`
	may use a cross over function for the construction
	of immigrants. If `function` has a parameter
	'cross_over_fct' it is automatically set to the function
	previously set with `set_cross_over`.

[TheChymera]

Yes, it's still not very clear what is set to which function, and what being set means. Do you mean the argument is passed to another function? as a **keyword argument?
