The constants definition file

The constants are defined in a file called constants.xml which is in the same directory as the program executable. The file's structure is as follows:

<Constants>
  <Constant>
    <Name>permeability</Name>
    <Abbreviation>µ0</Abbreviation>
    <Unit>H/m</Unit>
    <Value>1.25663706144e-6</Value>
  </Constant>
  <Constant>
    <Name>speed of light</Name>
    <Abbreviation>c</Abbreviation>
    <Unit>m/s</Unit>
    <Value>299792458</Value>
  </Constant>
</Constants>

The number of Constant entries is theoretically unlimited. Their order defines the order in which they appear on the constants form. The current element names are self explaining, although I will most likely make them shorter, in order to decrease the file size. Note that the unit is not used in the application yet.
