Implement the scaling Price Refinement heuristic in CostScaling (#417)
instead of Early Termination.

These two heuristics are similar, but the newer one is faster
and not only makes it possible to skip some epsilon phases, but
it can improve the performance of the other phases, as well.

\section naming_conv Naming Conventions
alpar@40
    24
alpar@40
    25
In order to make development easier we have made some conventions
alpar@40
    26
according to coding style. These include names of types, classes,
alpar@40
    27
functions, variables, constants and exceptions. If these conventions
alpar@40
    28
are met in one's code then it is easier to read and maintain
alpar@40
    29
it. Please comply with these conventions if you want to contribute
alpar@40
    30
developing LEMON library.
alpar@40
    31
alpar@40
    32
\note When the coding style requires the capitalization of an abbreviation,
alpar@40
    33
only the first letter should be upper case.
alpar@40

XmlReader
alpar@40
    37
\endcode
alpar@40
    38
alpar@40
    39
alpar@40
    40
\warning In some cases we diverge from these rules.
alpar@41
    41
This is primary done because STL uses different naming convention and
alpar@40
    42
in certain cases
alpar@40
    43
it is beneficial to provide STL compatible interface.

\subsection cs-files File Names
alpar@40
    46
alpar@40
    47
The header file names should look like the following.
alpar@40
    48
alpar@40
    49
\code
alpar@40
    50
header_file.h
alpar@40
    51
\endcode
alpar@40
    52
alpar@40
    53
Note that all standard LEMON headers are located in the \c lemon subdirectory,
alpar@40
    54
so you should include them from C++ source like this:
alpar@40
    55
alpar@40
    56
\code
alpar@40
    57
#include <lemon/header_file.h>
alpar@40
    58
\endcode
alpar@40
    59
alpar@40
    60
The source code files use the same style and they have '.cc' extension.
alpar@40
    61
alpar@40
    62
\code
alpar@40
