		 *

		 *
		 * If you want to create a directive using an unsigned integer:
		 * unsigned blarg;
		 * {"tag", "value", "0", new ValueContainerUInt(&conf->blarg), DT_UINTEGER, <validation>},
		 *
		 * If you want to create a directive using a string:
		 * Anope::string blarg;
		 * {"tag", "value", "", new ValueContainerString(&conf->blarg), DT_STRING, <validation>},
		 *
		 * If you want to create a directive using a boolean:
		 * bool blarg;
		 * {"tag", "value", "no", new ValueContainerBool(&conf->blarg), DT_BOOLEAN, <validation>},
		 *
		 * If you want to create a directive using a character pointer specifically to hold a hostname (this will call ValidateHostname automatically):
		 * char *blarg;
		 * {"tag", "value", "", new ValueContainerChar(&conf->blarg), DT_HOSTNAME, <validation>},
		 *
		 * If you want to create a directive using a character pointer that specifically can not have spaces in it (this will call ValidateNoSpaces automatically):
		 * char *blarg;
		 * {"tag", "value", "", new ValueContainerChar(&conf->blarg), DT_NOSPACES, <validation>},
		 *
		 * If you want to create a directive using a character pointer specifically to hold an IP address (this will call ValidateIP automatically):
		 * char *blarg;
		 * {"tag", "value", "", new ValueContainerChar(&conf->blarg), DT_IPADDRESS, <validation>},
		 *
		 * If you want to create a directive using a time (a time_t variable converted from a string):
		 * time_t blarg;
		 * {"tag", "value", "", new ValueContainterTime(&conf->blarg), DT_TIME, <validation>},
		 *
		 * For the second-to-last argument, you can or (|) in the following values:
		 * DT_NORELOAD - The variable can't be changed on a reload of the configuration
		 * DT_ALLOW_WILD - Allows wildcards/CIDR in DT_IPADDRESS
		 * DT_ALLOW_NEWLINE - Allows new line characters in DT_STRING
		 *
		 * We may need to add some other validation functions to handle certain things, we can handle that later.
