/** This service provides a widening converter converting from one type to another,
if possible.
<p>What is possible?
<ul>
<li>byte: byte, (short *1), (long *1), (hyper *1), (float *1), (double *1), (enum *2), (any *3), boolean, (char *4), (string *5)</li>
<li>short: byte, short, (long *1), (hyper *1), (float *7), (double *7), (enum *2), (any *3), boolean, char, (string *5)</li>
<li>long: byte, short, long, (hyper *1), (float *7), (double *7), enum, (any *3), boolean, char, (string *5)</li>
<li>hyper: byte, short, long, hyper, (float *7), (double *7), enum, (any *3), boolean, char, (string *5)</li>
<li>float: byte, short, long, hyper, float, (double *7), (enum *8), (any *3), boolean, char, (string *5)</li>
<li>double: byte, short, long, hyper, float, double, enum, (any *3), boolean, char, (string *5)</li>
<li>enum: (byte *9), (short *9), (long *9), (hyper *9), (float *9), (double *9), (enum *10), (any *3), (string *11)</li>
<li>void: ok for all types</li>
<li>any: ok for all types</li>
<li>boolean: byte, short, long, hyper, float, double, (any *3), boolean, char, (string *12). 0 => false, != 0 => true</li>
<li>char: byte, short, (long *1), (hyper *1), (float *7), (double *7), enum, (any *3), boolean, char, (string *13)</li>
<li>string: byte, short, long, hyper, float, double, enum, (any *3), boolean, char, string</li>
<li>struct: (any *3), (struct *14)</li>
<li>interface: (any *3), (struct *14)</li>
<li>exception: (any *3), (exception *14)</li>
<li>union: (any *3), (union *14)</li>
<li>sequence: (any *3), (sequence *15)</li>
</ul>
rules:
<ul>
<li>1: only converts if the value is in the range of the target type.</li>
<li>2: only converts if the value, not the position, of the enum is in the range of the target type.</li>
<li>3: get value until it is not an any. Then convert it with the other rules.</li>
<li>4: only converts if the value of the character is between 0 - 255.</li>
<li>5: only converts if the value represents a decimal, hexadecimal (0x...) or a floating point number.
Examples: 10, 0x10, 10.045, 10,555, +10, +10.6e10, -10.6e-10, .16.</li>
<li>7: only converts if the value is in the range of the target type.
The value is rounded to an integer.</li>
<li>8: only converts if the float can be converted back to the same enum value.</li>
<li>9: only converts if the number is one of the enumeration type values. Normally you need
reflection information of the enum type.</li>
<li>10: only converts if it is the same enumeration type.</li>
<li>11: only converts if the string contains the name of an enumeration type value. Normally you need
core reflection information of the enum type.</li>
<li>12: only converts if the value of the string is "1", "true" or "0", "false". The comparison
is case insensitive.</li>
<li>13: only converts if the length of the string is 1 or 0.</li>
<li>14: only converts if the types are equal or the source type is derived from the destination
type.</li>
<li>15: only converts if each element of the source sequence can be converted to an element
of the destination sequence.</li>
</ul>
