Creating bounding box for the geometry objects

[Sri Nagella]

To create methods that will be able to return bounding box for the geometry objects.

[Sri Nagella]

(In [1139]) Refs #170 Implemented Plane bounding box with tests

[Sri Nagella]

(In [1140]) Refs #170 Fixed Plane DBL_MAX its found in cfloat

[Sri Nagella]

(In [1141]) Refs #170 Implemented Sphere bounding box with tests

[Sri Nagella]

(In [1168]) Refs #170 Implemented Cylinder bounding box with tests, Rules, Object bounding box

Fixed Plane bounding box

[Sri Nagella]

(In [1169]) Refs #170 Fixed cfloat include in cylinder.cpp

[Sri Nagella]

(In [1170]) Refs #170 Fixed cfloat include in RulesTest.h

[Sri Nagella]

(In [1212]) Refs #170 Cached bounding box values

[Ronald Fowler]

(In [1223]) Added updates to ObjComponent for transformation of getBoundingBox and tests for this. Re #170

[Ronald Fowler]

(In [1230]) Bug fix to make treatment of tolerance consistent for Sphere.cpp and Cylinder.cpp with that for other surfaces. Also added extra tests close to tolerance level for most surfaces. Re #170

[Russell Taylor]

(In [1239]) Reinstated const-ness of Object object pointed to by ObjComponent. Conceptually, the Object methods being called are const, they are just caching some values. These variables have been declared mutable. Closes #170.

Reopened to tidy up tolerances in surfaces

[Ronald Fowler]

(In [1241]) Changed surfaces to use a single value for the tolerance, defined in Surface.h. Re #170

[Ronald Fowler]

(In [1242]) Extended getSurfaceTolerance to be used in Line, Track and Object. Track is slight question as it used 1e-5 not 1e-6 as tolerance, but tests are OK. Tidy up other methods. Also added a defineBoundingBox method for objects where getBoundingBox fails. Added tests for this. Re #170
