public File getGhidraInstallDir() {
		return new File(ghidraInstallDirCombo.getText());
	}
Gets the Ghidra installation directory.

@return The Ghidra installation directory.
  Could be null if unspecified, however, the page will not be valid until the Ghidra 
  installation directory is valid, so it should never be null when called by other 
  classes.
