Sameer Agarwal 9026d69d1c Allow SubsetParameterization to hold all parameters constant
1. SubsetParameterization can now be constructed such that all
parameters are constant. This is required for it be used as part
of a ProductParameterization to hold a part of parameter block
constant. For example, a parameter block consisting of a rotation
as a quaternion and a translation vector can now have a local
parameterization where the translation part is constant and the
quaternion part has a QuaternionParameterization associated with it.

2. The check for the tangent space of a parameterization being
positive dimensional. We were not doing this check up till now
and the user could accidentally create parameterizations like this
and create a problem for themselves. This will ensure that even
though one can construct a SubsetParameterization where all
parameters are constant, you cannot actually use it as a local
parameterization for an entire parameter block. Which is how
it was before, but the check was inside the SubsetParameterization
constructor.

3. Added more tests and refactored existing tests to be more
granular.

Sameer Agarwal a1019f6610 Use std::adjacent_find instead of std::unique
When detecting duplicates, it is more efficient to use std::adjacent_find
than it is to use std::unique.

Sameer Agarwal d9790e7789 Add ProductParameterization
Often a parameter block is the Cartesian product of a number of
manifolds. For example, a rigid transformation SE(3) = SO(3) x R^3
In such cases, where you have the local parameterization
of the individual manifolds available,
ProductParameterization can be used to construct a local
parameterization of the cartesian product.

Keir Mierle 7492b0d8de Update copyright headers with new year and URL
Since Ceres is moving to using GitHub for issues, and the Google
Code URL in the current copyright header will soon become invalid,
update all the headers.

Sameer Agarwal bcc865f81c Remove using namespace std;
For historical reasons we had a "using namespace std;" in port.h. This
is generally a bad idea. So removing it and along the way doing a bunch
of cpplint cleanup.
