CalculateFixture can include nested tables as both ''given'' and ''expected'' values.

This is expecially useful for writing calculation or constraint rules that involve domain objects and/or collections:
 * Nested collections are defined in the table form that's used with ''!-ArrayFixture-!'' (etc) and ''!-SetUpFixture-!''.
 * Nested domain objects are defined in the table form that's used with ''!-DomainObjectSetUpFixture-!'' and ''!-DomainObjectCheckFixture-!''

!3 Domain Objects
For example, to specify that a given object is expected from a calculation:
|!-fitlibrary.specify.NestedCalculateFixture-!|

|!-calculate-!|
|''x''|''y''||''point''|
|0|0||${pt00}|
|5|77||${pt577}|

For example, to specify that a calculation takes an object and results in some simple value:
|!-calculate-!|
|''point''||''x''|''y''|
|${pt577}||5|77|
|${pt00}||0|0|

For example, to specify that a calculation takes an object and returns another:
|!-calculate-!|
|''point''||''shifted point''|
|${pt577}||${pt678}|
|${pt00}||${pt11}|
!3 Collections of Domain Objects
For example, to specify that a given collection is expected from a calculation:
|!-calculate-!|
|''list''||''points''|
|0,0||${pts00}|
|1,2,3,4||${pts1234}|

For example, to specify that a calculation takes a collection and results in some simple value:
|!-calculate-!|
|''points''||''first x''|
|${pts00}||0|
|${pts1234}||1|

For example, to specify that a calculation takes a collection and returns another:
|!-calculate-!|
|''points''||''identity''|
|${pts00}||${pts00}|
|${pts1234}||${pts1234}|

|!-calculate-!|
|''set of points''||''identity''|
|${pts00}||${pts00}|
|${pts1234}||${pts1234}|

For example, to specify that the elements of a collection must be unique:
|!-calculate-!|
|''points''||''valid?''|
|${pts00}||true|
|${pts1234}||true|
|${pts0000}||false|

!3 Objects and Collections
For example, to specify that a point results in a collection of two of that point:
|!-calculate-!|
|''point''||''points''|
|${pt00}||${pts0000}|

|''expected test results''|39|''right''|0|''wrong''|0|''ignored''|0|''exceptions''|
